URGENT! PLS HELP FAST! Elena is trying to figure out how many movies she can download to her hard drive. The hard drive is supposed to hold 500 gigabytes of data, but 58 gigabytes are already taken up by other files. Each movie is 8 gigabytes. Elena wrote the inequality

a) Explain how you know Elena made a mistake based on her solution
